.Letters .Patent N0. 102,890, dated .Muy 1i), 1870.

The Schedule referred tovn these Letters Patent and making part of the same.

I, AARON WARD, of Dublin, Wayne county,'Indi ana, have invented a new andrusefnl Dropping-Attachment for Harvesters, ot' which the following is a specification. I 'l Nature and Objects of the Invention.

This is an improvement inthe class of grain-delivering mechanism of harvesters in which a shifting cradle` or platform receives the grain as fast as it is vcut and deposits the same in rear of or beyond the main frame, so as t-o be out 'of the way of the horses in the next through; vand my invention comprises an arrangement of parts for performing these functions with less wear and tear and with more ease and regularity than heretofore.

General @esm'fiptionA with Rcfereuce'to Drawings.

Figure l is a perspective rear view representing my dropper in position for receiving .the grain, the cut-off being elevated.

Figure 2 is a similar view, representing the same dropper in position for delivering the grain, the cut o being depressed. e

Figure 3 is a perspective front view of the operating gearing.

Figure 4 ,is a perspective view of the rack-driving spur-wheel with one of its bevcl-pinions. i

Figure 5 is a ,top view of the segment-wheel vwith the cut-ofi' treadle in section.

Figure (iv is a vertical section oithe dropper in the line ot' delivery.

Figure 7 is` a perspective rear `view. of the rackdriving spur-wheel. y i

` All the figures, except the iirst, show the parts in y the positions they severally assume at the instant of delivery, the first twoigures being on a smaller scale than-theothers.

AA represents a portion of the finger-bar provided with rearwardly-projecting hooked" lugs, B, which support and'guide` a rack, C, whose rearwardly-prolject-ing arms, D, support, about its-mid-width, the -tipping cradle E, vjaws, d, on the ends of thearms compelling said cradle to travel with the rack from right to left and back again.`

Aiso, extending rearward from the finger-bar, are arms, F, which support the left extremities of two bars, G, of rectangular transverse section, save at their notched triangular portions, g, and which, curving obiiquely rearward from -thcouter end of the tinger-bar for a short distance, as represented, extend thence leftward parallel with the ingenbar for a distance nearly equal to the stroke of the cradle.

The cradle E is provided beneath with two staples, H, which, encircling the bars G, serve, in conjunc- "tien with said bars, to guide and maintain the cradle bevel of the notches g from left to right co-'acts with thestaples H to restore the cradle to' its' horizontal position, which position it retains at all times, except at the outward termination of its stroke, asaforesaid. y

The rear portion of the cradle is composed of'a series of ingers, e, whose weight preponderates over 'that of the front portion of th-e cradle sufficiently to insure the tipping action as above.

The rack C is reciprocated by spur-wheel I, whose shaft J isarmed with a pair of similar bevel pinions, K, which, by meshing alternately with the segment L, on the front surface of the continuously-revolving wheel M, impart to the wheelI its said reciprocating action.

The wheel M may be,driven`by suitable geared connection, N, with the ground wheel.

Ou the rack C reaching either extremity' oi' its stroke, a projection, o, from a spring, O., is caused by piu I or pin P', projectingl from spur-wheel M, to enter an orifice, t or if, in the rack-driving wheel I, aud' thus prevent any accidental derangement or disturbance of the reciprocating parts during the opera tions of receiving and of depositing the grain. v

Hinged to the'ingenbar, or to projections therefrom, are two arms, Q, to whose free extremities are vpivoted the handles or hafts R, R'Iof a-cut-oi` board,

lV, which operates to temporarily A,catch and hold the grain while the cradle is out of theway.

One of the hafts, 1i, extends a short distance beyoudV the arm to which it is pivoted, so as to constitute the short end of a lever, and depending from this end is a trcadlc, S, which is confined in a guide, T, and terminates in a foot, U, which being at the proper juncture deprcssedby a projection, V, from the rear of the wheel M, operates to elevate the cntoi and to hold itin the elevated position while the cradle is in the condition for being charged with grain.

A notch, S, in the side of the. trcadle facilitates the escape oi' the latter from the action of the projection V, andA insures a prompt return oi" the cut-oi` to its receiving position. 1 Y

A shifting platform, or cradleoperated as above de-` scribed, is believed to be far preferable tosuch as operate by swinging in the arc oi' a circle in the loaded condition, so as to strain the machine and disturb its balance, and by reason of their great Weight to throw unnecessary labor on the team.

The rearward action by which the loaded cradle commences its stroke operates to disengage the butts of the grain from the sickle-bar.

My cradle, although here described as actuated by a rack, may obviously be reciprooated by a crank and pitman, or other equivalent device.

Claims.`

I claim as new, and of my invention- 1. rI he tipping cradle E, reciprocated by rack G, or' its equivalent, and guided by the notched and curved bars G grst obliquely rearward and then sidewise,

and tipped at its pointof delivery, substantially as set forth.

2. The combination oi' the tipping cradle E,cut

olf R R W, treadle S s U, and tappet V, substantially asset forth. y

3. The combination of the cradle E, rack C, and reciprocating mechanism,` substantially as set forth.

4. The projection P P,fspring O o, and orilices i i', in the rack-driving Wheel I, combined and operating substantially as and for the purpose set forth.

In testimony of which invention I hereunto set my hand.
